Final answer:
Option A and C: Two functions of lighting from a decorator's view are adding color and texture, and creating realistic or theatrical scenes.
Step-by-step explanation:
From a decorator's perspective, two functions of lighting are Adding color and texture and creating scenery or costume effects. Lighting can shape the intensity, color, direction, and texture to become influential, taking on the characteristics of a new location or altering the meaning of a character by changing the character's costume color and/or texture. For instance, a focused rectangle of light can simulate a jail cell, eliminating the need for actual bars. Additionally, lighting can create a realistic atmosphere by hiding the fixtures and tricking the audience into believing a single light source, like a 60-watt bulb on a table lamp, is illuminating the entire stage. Lighting design is an art that shapes how a story is received and understood by the audience. Modern fixtures have expanded the dynamic range of options available to lighting designers.
Moreover, the lighting design becomes another character in a play, animating the stage as it moves and changes, essential for guiding the audience's attention and enhancing the storyline. By effectively casting shadows, a lighting designer can subtly influence the storytelling. In modern times, LED and automated lighting fixtures have evolved the field, offering dynamic choices for panning, tilting, and adding texture to the stage, which requires detailed preparation from the lighting designer.
